Title: Measuring instrument for instantaneous fuel consumption - for motor vehicles, measures quantity proportional to supplied amount of fuel
Inventor: KURZ RUDOLF
IPC: G01F9/00
Filed: 1974-01-25
Abstract: The instrument also detects operating times of carburetors; instead of pressure measurement in the fuel feeding pipe, the suction in the fuel pipe between tank and fuel pump is taken as the quantity proportional to supplied fuel. Alternatively, instead of pressure measurement, the quantity of air sucked into the carburettor is taken as the quantity proportional to the amount of fuel delivered by the pump; the proportional term must correspond to the functional relation between the sucked in air and supplied fuel. Fuel flow rate is not measured directly, but a simple bellows is used to measure the pressure drop due to flow of air or fuel.

Patent DE-2459041-A1 (DE)
Title: Surface hardening of high carbon steel files - by diffusion of chromium, or chromium and titanium, to form carbides
Inventor: HASHIMOTO HIROSHI
IPC: C21D9/22
Filed: 1974-12-13
Abstract: In hardening a file made from steel high carbon content, the file is brought into contact with a metal such as Cr or Ti and heat-treated so that the Cr or Ti diffuses into the surface of the file, after which the surface is hardened. Normally, in the filing of moulds, dies and castings, a high carbon steel file soon wears and the serrations clog with filings due to magnetic attraction; for filing hardened steel, diamond files can be used but these are expensive and also become clogged. The present invention overcomes thse disadvantages. At least a tenfold increase in the life of carbon steel files is obtd. By the diffusion of Cr or Cr plus Ti in the surface of the file, not only is the surface hardness increased by the carbides formed, e.g. chromim carbide, are non-magnetic so far less clogging of the grooves or serrations occur.
